some measuring over 90 metres中measure为何不需要过去分词

It is so wet there that the trees are extremely tall, some measuring over 90 metres.

我了解some measuring over 90 metres.是独立主格，只不过有点不了解为何用measuring,而不需要过去分词呢?不是被测量吗?

measure除去可以是及物动词，还可以是连系动词。

《牛津》measure

linking verb+ nounto be a particular size, length, amount, etc.

The main bedroom measures 12ft by 15ft.

The pond measures about 2 metres across.

网友句子的独立主格结构中的measuring就是系动词。
